. and diffusion to water issuing therefrom.

Among the features of my invention vis the provision of an improvedbaille support offering very little, if any, obstruction to the water.With this construction the lsprinkler will not only cover an area oflarge circumference but will evenly sprinkle said area.

Another feature of my invention is improved adjusting means for thebaille permitting free but steady rotation thereof.

Another feature of my invention is extreme simplicity in constructionand design of the apparatus permitting cheap manufacture and assemblythereof.

Another feature of my invention is the provision of an improved'antifriction support for the sprinkler enabling it to be easily drawnover the lawn or other surface for change of position.

Other features and advantages of my invention will appear more fully asI proceed with my specification.

In that form of device embodying the features of my invention shown inthe accompanying drawing, Fig. 1 is a view in perspective'of the device;Fig. 2 is a view in side elevation of the upper end of the device; andFig. 3 is a View taken as indicated by the line 3 of Fig. 2. v

In that form of device embodying the features of my invention shown' inthe accompanying drawing, I0 indicates a vertical pipe with a jet II onthe upper end thereof. I2 indicates in general a rotatable baillesupported on the upper end of the jet and adapted to be engaged androtated by a stream of `water issuing from the jet. I3 indicates a thinbowed sheet metal supporting arm having its lowerend `connected to thejet and its upper end carrying a depending adjustable screw or trunnionI4 with its lower` end pointed and engaging a depression or socket I2ain the upper surface of the baille I2.

The lower end of the pipe I0 is supported on a horizontal base member I5with its ends bent downwardly as indicated by I5a carrying a roller IGmounted therebetween. The lower end of the pipe I0 is supplied from ahorizontal supply pipe Il connected to the hose I8. Y l

The wide roller I6 permits the'device to be drawn easily over a lawn orsoft surface by pulling the hose I3 without damage to the supportingsurface.

The member I3 is made of sheet metal which is of very thin gauge.Suiiicient strength and rigidity is obtained by making the member ofsubstantial width. The long dimension of the member is radial withrespect to the axis of the jet so water issuing therefrom encountersvery little, if any, obstruction from the member I3. In other words, themember I3 presents its thin edge to the direction of travel of the waterand therefore shades or obstructs the sprinkling action to a very iinedegree, if at al1.

-T'he upper end of the member I3 is bent at right angles as indicated byI3EL and perforated to receive the screw I4 vwhich is held in positionby the lock nuts I9-I 9.

The lower end of the member I3 is also bent at right angles as indicatedby I3b and also perforated to go over the jet II. It rests on theshoulder I I a of the jet and is held securely thereon by the nut 20.

The baille I2 has a thickened part or block I2J on its rear side whichcontains the `depression I2EL above described. The baille I2 has thegeneral shape of a propeller or fan blade designed to throw waterissuing from the jet radially and the baffle is unsymmetrical so thatwater issuing from the jet against the baffle will rotate the latter. Inorder to permit such rotation the lower end of the baille carries acollar I2c surrounding the upper end of the jet II and resting on thenut 20. The screw I4is adjusted to support the baille and permit freerotation thereof.

While I have shown and described certain embodiments of my invention, itis to be understood that it is` capable of many modifications. Changes,therefore, in the construction and arrangement may be made withoutdeparting from the spirit and scope of the invention as disclosed in theappended claims, in which it is intended to claim all novelty inherentin the invention as broadly as permissible, in view of the prior art.

What I claim as new and desire to secure by Letters Patent is:

1. A lawn sprinkler, including: a vertical pipe; a jet nozzle carried onthe upper end of the pipe having external threads thereon; a thin bowedsheet metal supporting arm having its major portion lying in a verticalplane radial to the axis of the jet nozzle, the lower end of said armbeing bent into a horizontal plane and perforated to receive the end ofthe jet nozzle through said perforation, the upper end of said arm alsobeing bent into a horizontal plane and perforated and lying over the jetnozzle; a lock nut on the jet nozzle holding the lower end of said armthereon a baille rotatably mounted on the jet nozzle; a bearing block onthe baille; and a depending through said perforation, the upper end ofsaid arm also being bent into a horizontal planeand perforated and lyingover the jet nozzle; means for holding the lower end of said arm on saidjet nozzle; a baille rotatably mounted on the jet nozzle; a bearingblock on the bale; and a depending trunnion adjustably mounted in theperforation in the upper end of said arm, the lower end of said trunnionengaging the bearing block on thebaie.
